Hi @paul-rogers, nice to see this code being encapsulated, standardized,
and unit tested. There seems to be a Travis test failure with your changes
though.
```
Failed tests:
TestOperatorRecordBatch.testNormalLifeCycle:156 expected null, but
was:<org.apache.drill.test.OperatorFixture$MockFragmentContext@45f1feca>
```
